Monday, 11 August 2008, Cassini will visit Enceladus to obtain the highest resolution images to date of the moon's enigmatic south polar region with its tiger stripes. Closest approach occurs at 21:06:19 UTC at an altitude of just 54 kilometres. This is Cassini's fifth close fly-by of Enceladus and the trajectory - taking it over both the...

On 4 August Rosetta starts to use its cameras to visually track asteroid Steins. These observations will be used to refine the trajectory of the spacecraft relative to Steins and to adjust it, if necessary, to achieve the desired fly-by conditions.

Just over two months after its last visit, the Cassini spacecraft once again approaches Titan for the mission's forty-sixth targeted encounter with the large Saturnian moon. This is the first Titan encounter in Cassini's Equinox Mission. The closest approach to Titan occurs on Thursday, 31 July, at 02:13:11 UT at an altitude of 1613 kilometres...

A nova explosion is usually detected first at optical wavelengths. The recent nova V598 Puppis, although being among the brightest novae, was instead discovered first in X-rays by XMM-Newton, some four months after the optical emission had peaked

The pericentre altitude of the Venus Express orbit is being lowered by a series of manoeuvres over a nearly four-week period with the spacecraft reaching a minimum altitude of 185 km in August. This will provide new science opportunities for the mission.
